I looked up what is a vector space online and it always gives like formula or long explanations. In a couple sentences can you tell me exactly what a vector space is? I know it has to go through the origin, but what else is true about a vector space?

Ive decided I am either going to take calculus 3 or the combo of linear algebra and differential equations. Which one do you think would be easier to go along with physics 2?

no, I am not quite sure what that equation is.

Homework Statement A glass window pane is 2.7 m high, 2.4 m wide and 2 mm thick. The temperature at the inner surface of the glass is and at the outer surface 4°C. How much heat is lost each hour through the window? The Attempt at a Solution I have the stats on the glass like...

it would those 3 and physics 2.

I currently go to a community college and they only offer these math classes during the spring spring and fall semester ( not during the summer semester). I just completed calculus 2 and I was thinking I could take differential equations, multivariable calculus, and linear algebra. Anyone else...

Homework Statement A tall tree and a short tree (both having the same width and mass density) are cut at the base at the same time, and begin tipping over. Which tree hits the ground first? The Attempt at a Solution I think they hit at the same time because gravity pulls on both...

Homework Statement A particle is moving in a circle. If the radius of the circle is doubled and the angular speed remains the same, then the angular momentum of the particle about the center of the circle will also be doubled. The Attempt at a Solution Im thinking it's false...

im still lost on this any inputs?

mgh+Nµ+(1/2)mv^2=(1/2)I(v/r)^2? I am so I am so confuded

Ok I got the circumference do I just multiply it by the radians?

im so confused is it then (1/2)mv2=(1/2)I(a/v)2+mu(d)+mgh?

what i got is this (1/2)(I)(v/r)^2=(1/2)mv^2 - friction?

where does the friction force come into the equation?

is it just radians x radius?
